I can see that the issue depend on
It's not the truth, it's opposite.
I have made a patch to add cvs edit feature
The patch is based on the 1.0 released (svn tag).
The fix impact 3 projects:
I have tested the both mode (native and command line) with success.
In fact the fix is in 2 parts:
1/ add the features into maven scm cvs plugins
2/ make a little patch because javacvs (netbeans) provide a default cvs command factory which does not include edit !!! (even the Edit command is present in the javacvs library ! ).
Let me know if you plan to include this in a next release.
PS: it's the first time i create a svn patch, if you want i can attach the complete source.
